Born in the Philippines and raised in Rockland County, New York, Teri was born into a family of professionals in the business and finance fields. However, her passion for health and wellness guided her into a different path.


    Teri's journey into the healthcare field began in 1998 when she graduated from The Swedish Institute with a Massage Therapy Certification.

Teri's career in massage therapy spanned an impressive 24 years, from 1998 to 2022.


    In 2011, driven by a thirst for knowledge and a desire to provide comprehensive care, Teri embarked on her nursing education. She graduated with honors in 2014, making the Dean’s List. As a Registered Nurse, Teri gained valuable experiences in long-term care, hospice, and mental health nursing.


    Teri's commitment to lifelong learning led her to further her education and she obtained a Master’s Degree in Nursing in 2020. As an Adult Health Nurse Practitioner, she has worked with patients suffering from digestive-related disorders and is now working closely with Dr. Lewis to design an optimal treatment plan to expedite the patient's recovery.


    In her free time, Teri continues to pursue educational opportunities to expand her knowledge and skills, always aiming to provide the best possible care to her patients.
